Azure Service Bus主题订阅服务器接收消息的顺序不正确

Question

I am using azure service bus topic and I have enable session for it's subscription.

With in the my logic app i am inserting data using sql transaction which are coming from topic I am using topic Subscription(peek-lock) and in subscriber level concurrency is set to default as follows

According to my Understanding, my logic app(subscriber) should read ALL the messages and have to processed in FIFO
my logic app is like

which means it should insert data to the table in ordered manner

however when i checked in the trigger log it shows correct order but in database level you can see the order is not happening

Answer 1

Message ordering is a delicate business. You can have either message ordering or concurrent processing, but not both. The moment you make message ordering a must, you lose the ability to have concurrent processing. This is correct for both, Azure Service Bus Sessions and Logic Apps concurrency control. You could process multiple sessions , but each session would be still restricted to a single processor. Here's a post about it.
